It could very well be the battery pack being out of balance and I wouldn't worry too much at vis time especially sins it is the first time and there is no massive drop in battery range.
Clear the fault codes and cycle the battery pack a few times (drive down to cero and recharge to full). If the fault cod P1C03 persists you clearly have a weak module (no. 14) in your HV battery back.
I am pretty sure this happened after I got an aftermarket charger to replace the one that came with the car. But its been charging perfectly fine as far as I know. I will try to clear codes and do a few charge cycles.
Any clue on P1200?
